Specification of Letters Patent.

Patented @ct. 2d, 119th.

Application filed January 2%, 1916. Serial No. 73,965.

To all whom it may concern:

Be it known that l, FRANK F. SCHULTE, a citizen of the United States, and resident of Albia, in the county of Monroe and State of Iowa, have invented a certain new and useful Milk-Can, of which the following is a specification.

The object of my invention is to provide a milk can of simple, durable and inexpensive construction.

A further object is to provide a milk can having a smooth interior curved at all points, so that there are no joints, seams or sharp bends on the interior of the can, which can can be thoroughly and easily cleaned, and kept sanitary.

A further object is to provide such a can having a thickened or reinforced bottom and a thickened or reinforced upper portion.

A further object is to provide such a can having a downwardly projectingcyhndrlcal portion at its lower end, and having a cover of novel construction whereby the cans can be stacked.

Still a further object is to provide such a can having a suitable reinforcing band mounted thereon just below the upper reinforced portion.

Still a further object is to provide such a can having coacting engaging means on the cover and the neck of the can, whereby the cover can be secured to the can and locked in position thereon, and also connected with the can by an ordmary seal or the like.

My invention consists in the construction, arrangement and combination of the various parts of the device whereby the ob ects contemplated are attained as hereinafter more fully set forth, pointed out 1n ny claims and illustrated in the accompanying drawings, in which: I

Figure 1 shows a side elevation of the can partly in section, embodying my lnventlon. Fig. 2 shows a top or plan v ew of the can with the cover removed. Fig. 3 shows a side elevation of the neck of the can, and Fig. 4 shows a detail, sectional view of a portion of the neck and cover of the can illustrating the locking means.

lln the illustration of my invention shown in the accompanying drawings, I have used the reference numeral 10 to indicate the upright central cylindrical portionpf my can. The body of my lmproved can 18 made of a single piece of metal without seams or sharp curves on the interior, and must be strong and tough and not brittle.

Formed on the lower end of the central portion 10 of the can is a thickened bottom member 11, curved from its lower central portion upwardly and outwardly in every dlrection. Formed on the outside of the wall of the can 10 at the lower end of the portion 10, is an upwardly extending annular rib or bead 12. Mounted on the lower end of the can is a cylindrical member 13 projecting downwardly below the bottom 11. The rib or bead 12 forms a shoulder which rests upon the cylindrical member 13 and is preferably soldered thereto or otherwise properly secured to the can.

At the upper end of the member 10 is a shoulder 14 of thicker material than the portion 10, and at the upper end of the shoulder 14 is a thickened neck 15. At the lower end of the shoulder 14, the lower portion of which is substantially cylindrical as shown in Fig. 1, thereis formed on the exterior of the can an annular shoulder 16. Spaced below the shoulder 16 is an annular rib 17. Mounted in the groove or slot formed between the shoulder 16 and rib 17 is an annular band 18 which is put on the can by first heating it and expanding it and then placing it on the can and then cooling said band. On opposite sides of the shoulder 14 are suitable handles 19. Tn the upper surfaces of theneck 15 is a groove 20 to receive a suitable gasket or the like 21.

The cover of my improved can comprises a comparatively flat member 22 of considerably greater diameter than the neck 15, having a downwardly extending flange 23 at its periphery, and having an inner downwardly extending flange 24 designed to fit around the outside of the upper portion of the neck as shown in Fig. 1.-

The flange 23 and neck 15 are provided with coacting segmental threads 24 and 25, shown in Figs. 3 and 4;, whereby the top can be secured on to the neck. The flange 24: is provided with a hole 26 designed to receive a strap 27 of a seal 28. The neck 15 is provided with a loop 29 for receiving said seal strap for locking the cover to the can by a seal.

The neck 15 is provided with an indentation 30 in its outer surface. Slidably mounted in a loop 31 mounted on the under Stireter than the -lower cylindrical member 13,

, flange 23 is a downwardly extending portion 35 formed on the portion 32 and adapted to serve as a handle. 'A'spring 36 secured to the portion '32 and to the flange 24 yieldingly holds the bolt 33 at one limit of its movement. The parts are so constructed that when the top is screwed onto the neck of the'can, the bolt 33 will be opposite the openin 30 and will slide into said open ng, from w ich it can be removed by pulling the handle 35 outwardly.

- The entire cover is of slightly less diamso that one can can be set' on top of the other with the cover of the lower can fitting just inside the member 13 for conveniently stacking the cans and holding them against tilting.

A can or container that has sharp corners, or one that has interior joints or seams provides points for the collection of dirt and germs and is extremely difficult to thorou hly clean and sterilize,

ne of the primary advantages of my improved milk can is its construction without any seams or the like on the interior and with a flat or curved inner surface, so that the can may be readily and easily and thoroughlywashed, scalded, and drained, so that it can be kept sanitary and sterilized.

Where a can is made with seams or joints, even though they are at first tight and smooth, the vibration and jar of use will loosen the seams or joints and make cracks which serve for the collection of dirt and bacteria even before the cracks are visible to ordinary inspectors. I

Another advantage lies in the method of mounting the cover on the can and of look ing it thereto. The cover is put on by an air tight joint,*so that the can after bein thoroughlv cleaned can be kept germ proo for storage or transportation.

Still another advantage arises from the arrangement of the bottom" and top of the can, whereby cans of this type may be conveniently stacked.

The arrangement of the projecting portion of the cover also protects the seal and the lock bolt 33.

Some changes may be made in the arrangement and construction of the parts of my improved milk can without departing from its essential features and purposes, and it is my intention to cover by this application any such changes which may be included within the scope of my claims.

I claim as my invention:

1. In a device of the class described, a

milk can having a smooth seamless interior and having an upwardly and inwardly curved shoulder at its upper end and an upwardly extended end at the upper end of the shoulder, the side walls of said can being substantially vertical, the bottom of said can and the lower wall member of. the said shoulder of said can being of greater thickness than the other portion of the vertical wall thereon, an annular cylindrical bottom member surrounding the bottom of said can and extending below the bottom thereof, the lower wall of said can having an annular bead'above said ring, and a cover for said can of smaller diameter than said can.

' 2. In a device of the class described, the combination of a milk can having a smooth interior and providedwith a contracted upper end having at its upper surface a re silient gasket, with a cover having on its lower surface a downwardly extending flange adapted to fit around said contracted neck, coacting screw-threads on the exterior of said neck and the interior of said flange for drawing said cover tightly against the neck for making a liquid tight joint, said FRANK B SCHULTE.
